The 1983: Doomsday Stories, or the "Doomsday-verse" is an Alternate Universe /AlternateHistory crossover between Axis Powers Hetalia and 1983: Doomsday, which follows the changing face of the world through the perspective of the Nations themselves, mainly around what was once Central Europe. But instead of dwelling on the destruction or major global players, the stories put more focus on how the Nations go about their lives and cope with their losses After the End, among others. And as time passes, new Nations are born, more realizations are made and Austria finally finds peace with an old love.

In part, it is inspired as well by this kink meme fanfic (definitely Safe For Work), also set in the Doomsday timeline, though following England's death. Said fic can also be found here.

The AU is still ongoing. So far, most of the stories primarily revolve around Austria, America, Prussia and Hungary, although a few fics focus on the British survivour nations or the Nordics, covering the years from 1983 to 2010 (though one fic takes place further down the line in 2031).

Ambiguous Innocence: Most of the Survivor Nations, including Sopron, can come across as this. Though they too were forced to go through the chaos that followed Doomsday, these new countries for the most part have far less trauma and baggage than the remaining Old World ones.

Back From the Dead: Angelic!Hungary. Though it's also hinted that England may become this as well.

Balkanize Me: England and (West) Germany left a good deal of Survivor-Nations in their wake.

Bedmate Reveal: Played with in One Unexpected Day. Prussia suspects that an oddly naked Austria might have had another bitter dream when the latter realizes that there's no one alongside him. Then Angelic!Hungary smacks the albino with her frying pan just as he's about to "comfort" him.

Big Brother Instinct: Features in What Family's For, with a total of three survivor nations coming to the aid of a younger sibling. England would be proud.

Body Horror: The stories don't shy away in describing how scarred (physically or otherwise) the remaining Nations are from either the bombs or the chaos. (West) Germany and Hungary, meanwhile, before they died were portrayed as burned, torn and warped almost beyond recognition.

Broad Strokes: The series doesn't strictly follow the source material (in part due to its wiki-style nature and origins), though it nonetheless tries to keep much of the spirit. Many details, such as those on Doomsday, in-verse countries and the more consistent elements of the timeline, are either preserved or played around with.

Brother-Sister Incest: Switzerland and Liechtenstein, which Austria very carefully tolerates, as much as the thought disturbs him. It's also stated in An Unexpected Union that Liechtenstein herself may have first initiated it.

Came Back Wrong: Averted. Angelic!Hungary makes a conscious effort not to come across as this, especially Her Guarding Arm.

Cozy Catastrophe: Subverted in the case of the Alpines. Neutrality spared most of their land and people from the bombs. This didn't stop the swarms of refugees or the struggle to fight off the chaos surrounded them. Neither did it stop the Soviets from destroying Vienna and attempting to invade Austria via Hungary. Then again, like in the source timeline, they also turn out to be one of the more dominant powers in the wasteland.

Crapsack World: In the immediate aftermath, just about everyone left alive is struggling to survive. Even further down the line, there are still large parts of the world that are still wasteland.

Determinator: The remaining "old world" Nations are pretty much this. Hungary herself applies. Even after she died.

Dark Fic: Just about any story or scene set in the 1980s. Especially Hungary's actual death.

Dirty Communists: Taking them out is how America tries to rationalize his involvement in Doomsday.

The Federation: The Alpine Confederation (Austria, Switzerland and Liechtenstein) serves this role along with True Neutral. Though in practice, it's implied that the siblings are the more dominant pair in the partnership. The "Nordic Union" (all the Nordics) is also implied to be this as well.

Great Offscreen War: Both Prussia's "Polish Adventure" and the Alpines' squabbles with Sicily/Romano are mentioned though never actually shown in action. On the other hand, the consequences of the former are expounded upon.

Guardian Angel: If Hungary's any indication in the Austria-centric tales.

Just Before the End: The Last Minutes to Midnight is all about this, showing a snapshot of what the world looked like just before everything went to hell in 1983. It culminates in Austria helplessly watching Doomsday unfold before his very eyes.

Noodle Incident: There are a number of references to events from the source timeline that are mentioned. One of the more common ones are to Prussia's "Polish Adventure," involving the "reconquest" of Pomerania and the subsequent asskicking from the Poles.

Proper Lady: Liechtenstein. Her pure, innocent and mature facade remains intact after Doomsday. But partly out of necessity and her eventual position as the heart of the Alpine Confederation, she also turns out physically older in the later-era stories. Her relationship with Switzerland meanwhile, at least in Austria's eyes, is anything but.

Prussia: It turned out that not only did he actually survive, but Doomsday had ironically given him a second chance at glory...though the first years were still painfully difficult.

Ragnarok Proofing: Varies, depending on the time period and setting. Though even relatively unharmed places show signs of neglect and decay.

Sanity Slippage: Doomsday wasn't exactly merciful to Poland (having developed a split personality) and Sicily/South Italy (who hasn't taken his brother's death all too well). While One Unexpected Day initially give the impression that Austria may have finally lost it. Thankfully, he didn't.

The Unintelligible: Cleveland, when he wants to be anyway. Actually true to the source material since the article on Cleveland includes a sample of the Clevish dialect which is nigh incomprehensible.

Time Abyss: This is hinted at to a degree by the 2000s-era stories, which Austria is trying to avoid. Though it's also stated that he had largely forgotten how Hungary sounded when she sang after all those years.

Title Drop: Her Guarding Arm is not only a reference to Hungary's national anthem, but also Angelic!Hungary's fate and role to Austria and Sopron at the end of the story.

Vestigial Empire: Despite being a core member of the Alpine Confederation, Austria still misses his old Imperial days (among others). Justified in a sense given that as in the source timeline, Switzerland (and to an extent Liechtenstein) holds greater influence having been completely untouched by the bombs. The same could be said of Prussia as well.

Who Wants to Live Forever?: Austria is inferred to have succumbed to this. He may have survived the bombs, but the nuclear death of Vienna and the eventual passing on of the pre-Doomsday generation as well as confirmation on Hungary's death left him with a bad case of grief and survivor guilt lasting decades. Granted, he does get better eventually.

World Half Full: By the 1990s and especially the early 21st Century, life is returning to something resembling normal. Humanity is rebuilding and starting anew. Still, many parts of the world are still in ruins, much remains to be done and not everyone's happy.
